ACT88321VU101SR

Overview

The Qorvo ACT88321VU101SR is a specialized Power Management IC (PMIC) designed for processor applications. It features three buck converters, two LDOs, and a load bypass switch within a WLCSP-30 package. The device operates with an input voltage range of 2.7 V to 5.5 V. Key electrical parameters include a maximum output current of 4 A, a maximum output voltage of 3.775 V, and a quiescent current of 260 uA. It supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Integrates three buck regulators, two LDOs, and a load bypass switch in a compact form factor.
• Supports configurable system-level sequencing and multiple wake-up triggers via GPIO.
• Enables real-time design debugging and setting changes without modifying external components.

Applications

• Solid-State Drives (SSD)
• Video processors
• FPGA systems

Procurement Notes

Verify the specific suffix 'SR' against official Qorvo documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with WLCSP-30 footprint requirements during PCB layout. Confirm that the selected variant meets the required thermal performance for the intended application environment.

Selection Notes

Select this PMIC when a high-density solution is required for processor power management. The integrated ActiveCiPS technology allows for flexible reconfiguration via I2C, reducing the need for multiple discrete components. Consider the 4 A output capability and wide input voltage range for robust system design.

Part Context

This component belongs to the ACT88321 series of advanced PMICs from Qorvo. These devices are part of the ActiveCiPS family, optimized for high performance and compact designs. The series targets applications requiring significant design flexibility and reduced board space through highly integrated power solutions.

Replacement Considerations

The ACT88329 is a publicly confirmed substitute within the same product family. Both devices share similar architectural features and target applications, though pinout and specific configuration options should be verified against datasheets before substitution.
